s l STATES;

VANIA.

ofv Pennsylvania, have invented a new and` useful Improvement sin 'ReenforcedConcrete Gonstruction, of Vwhichythe l'followmg 1s a full, clear, and exact description.

VThis invention relates to the art of reen-k forced concrete buildingl construction. It has'especial reference to that branch 'o'f the art in whichpreast blocksare joined in various Y combinations to form columns, bea1ns,girders, floors, andV other parts of a building'or other structure, andthe present improvements, relate more particularly to the means 'forconnecting adjoining blocks so. as to produce a strong rigid structure. The invention is illustrated in `the accompanying drawings `and will be hereinafter fully described, the novel features being subsequently particularly pointed out in the appended claims.k

vIn. the drawings: l y

.Figure V1 Vis an. elevation, partly broken away and partly in section', ofa portion of a building, illustrating my invention.;

Figure 2 is'an enlarged detail elevation, with parts broken away andin section, showing one connection between a tbeam and a supporting column.;

`Figure 3 is a perspective view, showing parts of the connecting elements illustrated in Figurer 2, on an enlarged scale; and

Figure t is adetail perspective view Iof a bracket Aillustrated in Figure las part ofthe connection. between abrace or strut and a column anda beam. c j y q In thegaccompan'ying drawings, the refer# ence numeral I indicates a 'pre-cast concrete block.` which is substantially rectangular in form and' may be produced ata central tplant and then shipped,'wl1en set, :to the point of use. These lbloclsmay be assembledin walls, columns, floors, beams, and other architectural elements and are constructed with openings or passages 2 entending en.- tirely therethrough so that the blocks, which maybe assembled'end to end to form a beam, may be clamped together by rods, indicated at 3, inserted-through the openings orpassages in allthe 1blocks and secured at their endsfwhereby the blocks will be firmly yheld together. "Theblocks may be provided in .BEENEORCED GONCRETE C0'NST.RU-C11320151 Application filed Aug/tst 25, 1922, 'SerialNa 584,311.

the blocksso as totie' the blockstogether,-

as will be readily understood'. oreover, grout may be poured through the alined vertical openings so as to'set around thereenforcing rods and ythereby aid in maintainingI the blocks in proper relation. In ureA l, I have shown the iblocks arranged to. fo'1m" c'olu1nns`6,fa beam 7', and a'strut or brace 8; fis clearly sli-own,` theblocks may be reduced linA their-horizontal dimensions above-the-'p'lane "of ithe beam sothatthe ends of the beam may 'be brought more or less over the lower portion'of the column and a firm support thereby provided. In order to provide amore extended support for the end ot theibeam, I employ elongated blocks '9 which I, for convenience, term bracket blocks and these blocks are similar in con-V structionto the blocks 1 but are elongated upon one diameter so that, when they areassembled in a column, asshown in 'Figure l, onev end will project laterally from the side o'f the column, and provide 'an extended support for the end of the superposed beam. In like manner, an elongated block may be inserted in the beam at proper intervals so as to provide an extended' support for the endv of a girder which'mayfbeconnected with the beam, such blocks being shown-at 10 in Figure 1.

have also shown in Figure l a portion of a floor composed of slabs lll which may also beof reenforced concrete cast at a central plant and shipped to the point-of use. These Slabs may be connected with the beams and girders upon w'hich they restbyreenforcements, indicated at l2, embedded in the beams or girders and extended up into the joints between adjacent slabsand suitably tied thereto.

In the embodiment ofthe invention illustrated in `Figure 1, the ends of the beam 7. are spaced from thesides ofthe column. The ends of' the reenforcing,T tierods 3 are disposed within the space V13 betweenthe beam and the column and are illustrated as equipped With nuts 14 WhichV are turned: home against connecting brackets or plates 15. Similar vconnecting plates or brackets 16 are .secured to the sides of the column by bolts extending transversely therethrough and the said plates or brackets, as shown more clearly in Figures 2 and 3, are provided with vertically disposed reenforcing ribs 17 upon their opposed faces which, when the parts are assembled, will stand side by side and through which fastening bolts 17 are inserted. After the plates have been secured to ther column and the beam respectively and to each other, as shown andv described, grout, indicated at 18, is poured into the space 13 so as to completely till the space and embed the said connecting plates, the resultbeing that, when the grout has set, a practically monolithic structure is attained. In Figure 2, I have also illustrated a reenforcing rod or connecting bolt 19 embedded in the blocks of the column and Y extending though thebase flange 20 of the connecting plate 15 so that the said connect- Ving plate Will be tied to the column at the bottom as Wellas to the side of the column, `and Vit will be readily noted that thev described construction mutually reenforces and braces the connecting plates as Well as the column and beam elements. 1

The strut 8 is ofcourse, disposed in oblique position and, Ilike the column and the beam, is composed of blocks 1 assembled end to end and held together by tie rods passing through the longitudinal passages in the blocks. Atthe ends of the strut, I provide brackets 21 which consist of triangular Webs 22 disposed between and preferably integral with attaching feet or pla-tes 23, said plates being provided with openings 24;' therethrough near their margins to receive the 'ends of the reenfo-rcing tie rods of the strut and of bolts embedded in the column and beam which may be equipped with, nuts turned home against the plates, as clearly shown in Figure 1, so that the brackets Will be secured to the ends of the brace Vor strut and to the beam and the column respectively. After the rparts lhave been assembled and secured, grout may be filled in 'between the plates 23 and. between and at the sides of the Webs 22 so that a. smooth exterior will be provided at the joint, false-Work of any convenient kind beingtemporarily set up to retain the grout in p-lace While it is setting. t ,i

Thi-le I have shown and described a preferred embodiment of my invention, it `will be understood that changes may bermade in the details of construction shown without departing from the spirit of the invention or scope ofthe appended claims. l
